A ecosystem It is a specific environment where the vital processes of a group of living beings are interrelated. The facts Biotics (such as animals, plants and microorganisms) and factors abiotic (air, water) are part of that shared environment.
The interdependent bodies that make up this unit establish food chains , which are currents of energy and nutrients produced through nutrition (a species feeds on the one that precedes it in the chain and, at the same time, is food for which it follows).
The notion of ecosystem, in general, is associated with natural ecosystem , where the biotic and the abiotic are in balance without intervention of the man . In any case, it should be noted that there are artificial ecosystems , which are created by the human being and that do not exist in the nature . A greenhouse, a dike and a fishbowl, for example, are examples of artificial ecosystems.
The broader acceptance of the concept of artificial ecosystem includes urban settlements such as cities , although these present several differences with natural ecosystems.
Among the main hallmarks that are characteristic of any artificial ecosystem, we must say that there is the fact that any aspect or condition of the mentioned ecosystem can be modified by the will and action of man. In this way, for example the soil would be one of those modifiable conditions since the human being alters it with fertilizers, changes the crops that develop in it ...
Another of the main characteristics that an artificial ecosystem has is the fact that in it the individual needs to provide himself with sources of artificial energies, in addition to the one he has through the Sun. And it is that thanks to those it is how he can operate the different devices you have to survive such as boilers or lighting.
Nor should we forget that within this type of ecosystem that we are analyzing in greater depth there are a number of elements that are called biotic or abiotic. Specifically, three large groups are established:
Biotic factors. This classification includes both the animals that are raised there and the plants that are grown.
Natural Abiotic Factors On the other hand, under this denomination are such elements of Mother Nature as they are the earth, the water, the rain or the air.
Abiotic Factors In this case, this term refers to man-made constructions such as houses, dams, bridges or buildings in general.
The modification of a natural ecosystem by man can also generate an artificial ecosystem. A natural ecosystem that suffers the extinction of a species by human action already loses its original condition, so it can be considered an artificial ecosystem or, at least, a modified natural ecosystem .
It must be borne in mind that the modification of natural ecosystems usually has consequences such as desertification and the emergence of pests , affecting biodiversity and natural resources.
